Title: High avalanche breakdown strength mosfet and its manufacture
Inventor: TEZUKA TOSHIKAZU
IPC: H01L29/78
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To provide an MOSFET of high avalanche breakdown strength. SOLUTION: A breakdown voltage of a tubular junction part 92 of a channel region 63 of a double diffusion longitudinal MOSFET is made at most a breakdown voltage of a spherical junction part 91. When a p-n junction breaks down by reverse electromotive force of inductive load, the tubular junction part 92 of a large area breaks down and avalanche current flows in the part, thus improving breakdown strength. It is desirable to provide an avalanche breakdown induced layer 58 which has the same conductivity type as a drain region and high impurity concentration between opposite sides of the channel diffusion layer 63 for keeping breakdown strength of the tubular junction part 92 low.

IPC: B21D5/14
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To prevent deflection/deformation due to the load of the dead weight by automatically adjusting the optimum position for each product dimension so that a work may be properly supported at the height and horizontal position of a double-receiving roller in accordance with the progress of forming and thereby accurately supporting the work during the forming regardless of the change in the product dimension. SOLUTION: At first, a pattern decided for each product scheduled this time are inputted in a CPU 5 as an initial condition in starting forming. By receiving this input, an operation signal of a hydraulic cylinder 22 is outputted; an elevation body 3 starts elevation and its moving quantity is momentarily replaced with the number of revolutions of a sprocket 24 engaging with a roller chain 25 and detected by a pulse encoder 51; and, when that detection is inputted in the CPU 5 through a circuit, the CPU makes calculation, compare with a set value and, when it coincides with the vertical height of the target, outputs a stop signal. As a result, the hydraulic cylinder 22 receiving this signal stops its operation, so that the elevation body 3 stops at the set position and that receiving rollers 4A, 4B are positioned at a desired height.

Title: Pneumatic radial tire
Inventor: HAMAMOTO KIMIYA
IPC: B60C11/01
Filed: 1993-09-13
Abstract: PURPOSE:To promote a reduction in heel-and-toe abrasion to be produced in a block and a lug by setting up each sipe, different in length extending in the tire width direction, in the block and the lug as the longest one is the rear side in the tire rotational direction and the shorter one in order subsequently. CONSTITUTION:Each rib 3 sorted by main grooves 1 is set up in a center part of a tread part, and each sub groove 2 is inclined and installed in both symmetrical shoulder parts from the main groove 1 at the outermost side so as to make it widen toward the rear side to the tire rotational direction. In addition, each sipe 7 different in length of tire width direction components is set up stepwise in each of blocks 4 formed in this way, and the longest one is set up at the rear side in the tire rotational direction and then the shorter one in order subsequently. Accordingly, rigidity at the rear end side is smaller than that of at the front end side, so at the time of driving, frictional force to grow larger at the front end side is dispersed around and thus any partial abrasion at the operated side is restrainable.

IPC: B65F3/20
Filed: 1987-09-11
Abstract: PURPOSE:To smooth an operation and prevent loss time and malfunction of a garbage truck with a centerless type garbage loader by operating simultaneously a raking panel and vertically moving panel when raking cylinder working oil pressure exceeds a set pressure during raking operation. CONSTITUTION:When an irrational force acts on a raking panel during raking dust in a raking process, pressure in a pipe line 15 exceeds a set pressure. Thus, the contact of a pressure switch PS is closed, and after a predetermined time a solenoid SOLb is energized to operate a vertically movable cylinder 5 and lift a vertically movable panel. During that time a solenoid SOLc is continuously energized to continue the operation of raking panel. The pressure switch PS is turned off by the reduction of pressure to stop said vertically movable panel. Thus, the operation is smoothed to prevent any malfunction and loss time.

Title: Device for installing battery
Inventor: KUROHARA TAKASHI
IPC: H01M2/10
Filed: 1990-08-30
Abstract: PURPOSE:To prevent operation of equipment batteries are not installed by detecting a voltage from a battery installing portion, and controlling a CPU into a nonoperative state if the voltage is below a predetermined voltage value. CONSTITUTION:Four batteries 21a to 21d are initially installed in respective installing portions 32 to 32d. When one of the batteries is removed and voltage from the installing portions 32a, 32b is detected by a VDT 25 and when the voltage is lower than a predetermined value the VDT 25 transmits an interrupt signal IRQ to a CPU 22 which transmits a chip disable (inhibit) signal CD to a RAM 23 so as to inhibit writing of data into the RAM 23. Since the batteries 21c, 21d are being installed in the respective installing portions 32c, 32d, erasing of data stored in the RAM 23 can be prevented. Even if the CPU 22 operates erroneously, an OR gate 27 inhibits writing of data into the RAM 23, whereby reliability can be enhanced from the point of view of protection of the data stored in the RAM 23.

Abstract: PURPOSE: To make it possible to measure the decentering of an aspherical lens simply by providing a holding means, which supports the lens under inspection on the side of the spherical surface so that the center of curvature of the spherical surface becomes the specified position. CONSTITUTION: A holding means 3 holds a lens under inspection 1, whose one surface 1a is aspherical and other surface 1b is spherical, so that the center of curvature of the surface 1b is set at the specified position, at the side of the surface 1b. The light from a light source 4 is reflected from a half mirror 5, made to be the parallel luminous flux with a condenser lens 6, transformed into the convergent luminous flux with a condenser lens 7 and applied on the surface 1a of the lens under inspection 1. The irradiated light is reflected from the surface 1a, transmitted through the lenses 7 and 6 and the mirror 5 and made to pass through an opening 8a of a light screening member 8. The image of the light is formed on a light receiving surface 9. The light receiving surface 9 is a reticle, wherein a scale 9a is printed.  Under the state, wherein the optical axis is aligned in this way, the luminous flux passed through the opening 8a is obtained as the ring image. The decentering amount and the decentering direction of the aspherical surface of the lens under inspection 1 are measured based on the deviated amount and the deviating direction of the center of the ring image from the optical axis.
